Question
A rectangular field is 20 m long and 14 m wide. There is a path of equal width all around it, having an area of 111 sq m . Find the width of the path.
Answer · 48 votes
Let width of path x Length = 20 + 2x Width = 14 + 2x Area of outer rectangular = l × b l = ( 20 + 2x ) ( 14 + 2x ) = 4x^2 + 68x + 280 Area of path: 4x^2 + 68x + 280 - 280 = 111 4x^2 + 68x = 111 4x^2 + 68x - 111 = 0 (4x^2+74x-6x-111) = 0 (2x - 3)(2x + 37) = 0 x = 32 m or x = - 372 Since, width can not be - ve Hence, the width is 1.5 m .
